Last week a site I've been working on for a couple of months went live - www.journalonline.co.uk. Developed for the Law Society of Scotland and working with Connect Communications, the site is an online resource of information that appears in the printed magazine 'The Journal'.
The site is entirely developed in ASP.NET (using c#) and has a SQL Server 2000 backend. I made use of Paul Wilson's master pages for maintaining the site templates, and also used the Data Provider and Configuration Management application blocks. Note that if you plan to use the Configuration Management application blosk, I strongly recommend you check out the forum on the gotdotnet site where the component is hosted - there are a number of known issues with it.
The search facility provided on the site (to search the library of articles) makes use of a Full Text Index. Having used Index Server a number of times in the past to provide search facilities, I understood the ease of integration this approach would offer, and the in built facility for ranking results. It was also a low cost solution, as no third party software was required. The main downside can be the performance of the index population, but in this case that wasn't an issue as the frequency of updates was low.
The backend of the system also uses FreeTextBox (the same component used to manage this blog!).
Feel free to have a look and let me know what you think!
